The connecting rod is liollovred out to reduce its Weight and to provide a groove or channel to convey the lubricant to the cross head pin. i

The main driving` shaft Q2 has one bearing i3 in the sider of the case .2 and has its end jouriialled in the removable bearing` member Ql-,'which fits Within the opening, 25, being held in place therein by means of the plugl .li-lin 2i' yconnects plue 26 to the bearing member "lll, so that as the plug is screwed into pos' "ion, the bearing member is moved .into position and held'there against rotating. )Drivey pinion 28 .is secured on shaft 22 and meshes with the large gear ll, as shown. rl-he opening 25 is large enough to permit the ready removal of ,Crear 2S land bearing QA therethru.

The principal features are the simplicity and strength of the construction, the accessibility of the parts, the entire enclosing of the mechanism, and the readiness with which it may be taken apart. riliis only involves the removall of the cap plate or coverf), the bearing cap l?, the studs or short shafts lO, and disconnecting the piston. Then all of the operating parts kmay be removed through the opening lef-t by the removal of the vcap or cover plate 9,
